Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic, inflammatory skin condition that affects the apocrine sweat glands. Accurate diagnosis is crucial for effective management and treatment. In medical coding and billing, the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code L73.2 is used to specifically identify hidradenitis suppurativa. This article provides an overview of the diagnosis code L73.2 and its significance in understanding and addressing HS.
What is Hidradenitis Suppurativa (HS)?
Hidradenitis suppurativa is a long-term skin condition characterized by painful, boil-like lumps that form under the skin. These typically occur in areas where skin rubs together, such as the armpits, groin, buttocks, and under the breasts. The condition arises from inflammation and blockage of hair follicles and apocrine sweat glands.
Symptoms of hidradenitis suppurativa can vary in severity but commonly include:
- Blackheads: Small pitted areas of skin with blackheads often appearing in pairs or a double-ended configuration.
- Red, Tender Bumps (Abscesses): Painful, pea-sized to marble-sized lumps that can feel firm and tender to the touch. These abscesses may enlarge, break open, and drain pus.
- Tunnels (Sinus Tracts): Over time, recurring abscesses can lead to the formation of tunnels under the skin. These tunnels connect abscesses and can drain pus, leading to odor and discomfort.
- Scarring: As the cycle of inflammation and healing repeats, hidradenitis suppurativa can cause permanent scarring. The scars can become thick and pitted.
Understanding the ICD-10-CM diagnosis code L73.2 for Hidradenitis Suppurativa, a chronic skin condition.
The exact cause of hidradenitis suppurativa is not fully understood, but it is not caused by poor hygiene. Factors that may contribute to HS include genetics, hormonal influences, smoking, and obesity. It is more prevalent in women, African Americans, and individuals with a history of acne.
Decoding ICD-10-CM Code L73.2
ICD-10-CM code L73.2 is the designated medical code for “Hidradenitis suppurativa.” This code is part of the broader category L73, which encompasses “Other follicular disorders.” Specifically, L73.2 is a:
- Billable/Specific Code: This means L73.2 is precise enough to be used for diagnosis coding on billing claims. It directly indicates a diagnosis of hidradenitis suppurativa for reimbursement purposes.
- Recognized in ICD-10-CM 2025: The code L73.2 is valid and has been in use since the 2016 ICD-10-CM edition, with no changes through the 2025 edition effective October 1, 2024. This demonstrates the established and ongoing recognition of hidradenitis suppurativa as a distinct medical condition.
Using ICD-10-CM code L73.2 ensures accurate medical record-keeping and facilitates appropriate billing and insurance claims related to the diagnosis and treatment of hidradenitis suppurativa.
Diagnosis and Management of Hidradenitis Suppurativa
Diagnosing hidradenitis suppurativa typically involves a clinical examination by a dermatologist or healthcare professional. There is no specific lab test to diagnose HS; diagnosis is primarily based on the characteristic appearance of lesions, their location, and the patient’s medical history.
Management of hidradenitis suppurativa aims to control symptoms, prevent disease progression, and improve the patient’s quality of life. Treatment approaches can vary depending on the severity of the condition and may include:
- Antibiotics: To manage bacterial infections associated with HS lesions.
- Anti-inflammatory Medications: To reduce inflammation and pain.
- Steroids: Injections or oral steroids may be used to control flare-ups.
- Biologic Medications: For more severe cases, biologic drugs that target specific parts of the immune system may be prescribed.
- Surgery: Surgical options range from drainage of abscesses to excision of affected skin areas in severe cases.
- Lifestyle Modifications: Weight loss (if overweight or obese), smoking cessation, and wearing loose clothing can help manage symptoms.
Conclusion
Understanding the Diagnosis Code For Hidradenitis suppurativa, ICD-10-CM L73.2, is essential for healthcare providers, medical coders, and individuals affected by this chronic condition. Accurate coding ensures proper documentation, billing, and tracking of hidradenitis suppurativa. If you suspect you may have hidradenitis suppurativa, it is important to consult with a healthcare professional for proper diagnosis and a personalized management plan. Early diagnosis and treatment can help manage symptoms and improve long-term outcomes.
